fix(lambda): enable template parameter prompters for all deploy and sync entry points

[vicheey]

Problem

When deploying a template with parameters, SAM guided action prompts customers to confirm to either use default value or update to a new value values. Such prompters for template parameters value only exist for Deploy Wizard when invoke from : 1). Template file context menu, 2). App builder node deploy button.

Such prompter is missing in

• Deploy Wizard entry points:
  1. Command palette entry points
  2. Region node context menu
• Sync Wizard entry points:
  1. Command palette
  2. Region node context menu
  3. Template file context menu
  4. Samconfig file context menu
  5. App Builder node deploy button

Solution

• Implement nested wizard for template parameter for both sync and deploy action for all entry points.
• Refactor DeployWizard class for consistency with SyncWizard class
• Add unit test for validating correct backward flow and state restoration for both wizard.
